What are the GHS Physical Hazards (Workers Need to Know)

Janet Cornett July 25, 2018 0

The Globally Harmonized System of Classification and Labeling of Chemicals (GHS) provides standards for the labeling and classification of chemicals. Some of the physical hazards the standard protects against range from injurious to life threatening and are as follows.

Explosives

A substance or mixture that is explosive is a liquid or solid which undergoes a volatile chemical reaction. The reaction produces gases at temperatures, pressure and speed that damages surroundings. This includes pyrotechnic materials even if they do not generate gases.

This mixture produces an effect via heat, light, sound, smoke or gas or a mixture of all of those effects resulting in non-detonative and self sustaining reaction.

 Flammable gases

By flammable gases we mean gases that can reach a flammable range of 20°C and at 101.3 kPA pressure. Materials and mixtures that come under this class are based on 2 categories of hazards which are based on the calculation method and results.

Aerosols

Flammable aerosols include any gas that is dissolved, liquefied or compressed under immense pressure in a container that is made out of plastic, glass or metal. The non-refillable container also has a release mechanism that allows its contents to eject in the form of liquid or solid particles in a suspended paste, powder, gas or foam state.

Oxidizing gases

This includes any gas which may contribute to a combustion reaction of another material. Substances that come under this category are unique since they can contribute to the combustion of another substance just by providing oxygen. That is why several hazard communication standards perceive oxidizers as a class of chemicals.

Pressurized gases

Pressurized gases are kept in containers under pressure that does not go below 280 Pa. This includes 4 types of gases or mixtures which may cause damages due to sudden release. If released, the gases can cause significant damage to people, the environment or property.

GHS and OSHA Hazardous Communication

Your workers are exposed to these hazards and more at the workplace on a regular basis. Chemical hazards in particular can lead to serious injuries and exposure can also prove fatal. The GHS and OSHA Hazardous Communication course from 360training.com gives students a basic understanding of these hazards and how to remain safe from them.
